Formed in the housing15 adjacent the rear end of th enin 17, is a artition rin 30. This rin bb D tomary transmission plate mounting the bearings for the forward endsof the'shafts 25 and 26. Thus, after the usual transmission housing andrear axle of the tractor have been removed, the housing 15 may bereadily substituted in lieu thereof and the transmission of the tractorassembled within the latter housing to be supported thereby in the samemanner and relation accomplished by the standard housing. At the sametime, the rear axle of the tractor and associated parts will beeliminated so that the power unit may, as shown in Figure 1, be readilypositioned between the side bars 10 of the truck chassis at the forwardend thereof. Extending between said side bars beneath. the forward endof the power unit is a cradle 31 supporting the power unit at itsforward end. Riveted or otherwise secured to the side bars 10 of thetruck chassis are, as shown in detail in Figure 5, rackets springs 35bearing against the arms, these springs being employed to prevent unduebinding between the parts. Formed in the rear end portion of the housing15 at the left side thereof, as seen in Figure 1 of the drawings, is asuitable opening and closing sald opening is the usual gear shifterplate 36 of the tractor bolted to the housing. The plate 36 mounts theusual gear shifter assembly cooperating with the movable gears of thetransmission and includes the gear shift 1ever 37 which may be manuallyoperated for shifting the gears. V

Bolted to the boss 22 of the housing 15. over the opening 23 in saidboss is a rearwardly extending cap 38 housing the projecting end of thehub 29 of the gear 27. Normally, said hub receives one end of the wormshaft of the rear axle of the tractor. However, in accordance with thepresent invention, said worm shaft is eliminated and in lieu thereof Iprovide a replacement shaft 39 splined at itsinner end in the hub toproject through the end wall of the cap 38 and provided with a taperedouter end 40 terminating in a stud. 41. Formed on the shaft to confrontupon which itis keyed and secured against displacement by a nut 47 uponthe stud 11.

Thus, the power unit will be operatively con nected with the propellershaft of the truck chassis so that said unit may be operated and thetransmission gears of the unit set for driving the truckformed by theassembled power unit and chassis. At the same time, space will beconserved and the presence of unnecessary parts avoided by theelimination of the rear axle and associate mechanism of the tractor.

Having thus described the invention, what is claimed as new is:

1. In a motor vehicle, the combination with a chassishaving propellingmechanism including a propeller shaft, and a tractor including a powerunit and transmission embodying a transmission gear having a hub andfrom which tractor the wheels and axles as well as the transmissionhousing and rear axle housing have been removed, of a replacementtransmission housingfsecured to the power unit mounting saidtransimssion and having a rear end wall apertured to receive said gearhub. therethrough, means mounting the. unit with said replacementhousing thereon upon the chassis, a stubshaftfitting at one endin saidhub and connected at its opposite end with said propeller shaft couplingthe transmission with the propeller shaft, a caplsecured to said endwall of the replacement housing over saidv opening and surrounding thestub shaft, and a bearing mounted within the cap and journaling the stubshaft.

2. In a motorrvehicle, a replacement shaft splined at one end forengagement in the hub of a. transmission gear and formed-at the base ofits splined portion with a collar, the opposite end of the shaft beingshaped to receive a universal joint and being provided with a terminalstud.

3. In a motor vehicle, the combination with a chassis having a propellershaft, of a power unit mountedupon the chassis and in cluding atransmission having a driven gear provided with a hub, a replacementhousing secured to the power unit mounting said transmision andjournaling the hub of said gear therethrough, and a replacement shaftengaged in said hub and fconnectingthe transmission with saidpropellershaft.
